With 21 marbles in the bag, and 9 of them green, her chances are 9/21 that she will pull a green marble. If you reduce 9/21 you get 3/7 which is the way the answer should be expressed (in lowest terms)
Answer Probability of green = 3/7
F the diameter is 1/2 mile, that is 0.5 mile, then the radius is 0.25 -half of it!
the angular speed is theta/time, which means
w=theta/time
but another formula for it is Velocity*radians
w=velocity*radians
velocity is 180 mph and radians are (revolution/2 radius), that is:
w=180*(1/2*0.25)
and if we calculate this, we have: w=114.59, which is the correct answer!
Answer:
D
Step-by-step explanation:
X is 21
z is the same as 111
y is 48
Answer:
5n + 12
Step-by-step explanation:
Perform the indicated multiplication. Then combine like terms:
2n + 3n + 12 = 5n + 12 (answer)
To solve the problem, substitute the given points for x in the given equation to get
Solving the three equations simultaneously, we have:
a = -3, b = 2 and c = -5
Therefore, the required equation is
